The Bombay High Court has clarified that a remand order in patent prosecution, issued to cure a breach of natural justice, cannot be used as a vehicle to reopen the examination process by introducing entirely new objections or prior art references. The judgment reinforces that remand is procedural, not substantive, and confines the authority to the scope of the original record.
Background & Facts
The Dispute
The Applicant, Qualyst Transporter Solutions LLC, filed Indian Patent Application No. 201727011198 seeking protection for a technical invention. The patent examination process spanned nearly a decade, beginning with the issuance of the First Examination Report (FER) on 22.12.2020. The Applicant filed a detailed response with substantive claim amendments on 21.06.2021. Subsequent hearing notices were issued on 25.08.2021 and 21.09.2021, indicating the conclusion of the examination stage.
Key Facts
- The FER dated 22.12.2020 contained initial objections under Sections 2(1)(ja), 3(i), 10(4)(c), and 10(5) of the Patents Act, 1970.
- The Applicant’s response dated 21.06.2021 addressed all objections raised in the FER.
- Hearing notices dated 25.08.2021 and 21.09.2021 confirmed the examination phase was complete.
- On 25.10.2021, a hearing was held where the Controller raised new objections for the first time orally, without prior written notice.
- The Controller issued an order dated 15.07.2025 refusing the patent based on these newly introduced objections.
- The Applicant challenged this order before the Bombay High Court.
Procedural History
- 15.07.2025: Controller issued refusal order based on objections raised for the first time at the hearing.
- 15.10.2025: Bombay High Court passed Order of Remand, setting aside the refusal order on grounds of violation of natural justice. The Court directed a fresh hearing within three months before an independent Controller.
- 16.01.2026: Respondent issued a new hearing notice introducing entirely new objections under Sections 2(1)(ja), 3(i), 10(4)(c), and 10(5), along with six new prior art references (D1 to D6) not previously in the record.
- 20.03.2026: Hearing scheduled under the new notice.
- 05.04.2026: Interim Application No. 1778 of 2026 filed seeking clarification that the remand order barred introduction of new objections.
- 08.05.2026: Judgment reserved.
- 15.06.2026: Judgment pronounced.
The Parties' Positions
The Applicant contended that the remand order was narrowly confined to providing a fair hearing on objections already in the record. The Respondent, the Assistant Controller of Patents & Designs, argued that the remand did not restrict its statutory power to raise new objections under the Patents Act and Circular No. 4 of 2011.
Relief Sought
The Applicant sought:
- Clarification that the remand order permits only reconsideration of objections already in the record;
- Stay of the hearing notice dated 16.01.2026 to the extent it introduces new objections;
- Direction to the Respondent to proceed strictly within the scope of the remand;
- Any further relief deemed appropriate.
The Legal Issue
The central question was whether a remand order issued to cure a breach of natural justice in patent prosecution permits the Controller to introduce entirely new objections or prior art references not part of the original examination record, or whether the remand is confined to providing a fair hearing on objections already raised.
Arguments Presented
For the Petitioner
Mr. Khandekar submitted that the Order of Remand was unambiguous: it set aside the refusal order solely due to the violation of natural justice caused by raising objections for the first time at the hearing. He argued that the examination process had concluded in 2021, and the remand was not a license to restart examination. He relied on Shree Champalal Kothari Trust v. Rajhans Cooperative Housing Society Ltd., Shivshankara v. H.P. Vedavyasa Char, and Laxman Bapu Berad v. Sudhakar Nanasaheb Jawale to establish that remand orders bind authorities to their specific terms. He further cited Euro-Apex B.V. v. Controller of Patents and Designs, Grupo Petrotemex S.A. de C.V. v. Controller of Patents, and Kamterter Products LLC v. Assistant Controller of Patents to show that Indian courts have consistently held that remand in patent matters requires fresh consideration on the existing record, not introduction of new prior art.
For the Respondent
Mr. Deshmukh contended that the Order of Remand was silent on restricting future objections and therefore conferred no such limitation. He relied on Circular No. 4 of 2011, which permits Controllers to raise new objections via hearing notices without issuing a second FER. He cited Perkinelmer Health Sciences Inc. v. Controller of Patents, Otsuka Pharmaceutical Co. Ltd. v. Controller of Patents, and Bayer Pharm Aktiengesellschaft v. Controller General of Patents and Designs to argue that the Controller’s statutory duty to ensure patentability overrides procedural constraints from civil litigation. He asserted that patent prosecution involves public interest and rights in rem, and thus private law doctrines on remand do not apply.
The Court's Analysis
The Court began by acknowledging the Respondent’s argument that the Controller possesses broad statutory powers under Sections 12 to 15 and 43 of the Patents Act, and that Circular No. 4 of 2011 permits raising new objections via hearing notices. However, the Court emphasized that the issue was not about general powers, but about the scope of a specific remand order.
"The question, which falls for consideration in the present case, is whether those principles would apply in the facts of the present case, given the remit and scope of the Order of Remand. In my view, they would not."
The Court noted that the Order of Remand was passed only because the Respondent conceded that natural justice had been violated by raising objections orally for the first time. There was no suggestion from the Controller that the examination was incomplete or that further prior art needed to be considered. The direction to conclude the fresh hearing within three months indicated that the examination phase was already over.
The Court rejected the Respondent’s reliance on Perkinelmer and similar cases, distinguishing them on the ground that those cases involved initial refusal orders where objections were not communicated in writing. In contrast, this case involved a remand order with a specific, limited purpose: to cure a procedural defect, not to restart examination.
"The direction that the matter be 'considered afresh' must therefore be understood as requiring a fresh hearing after granting the Petitioner an opportunity to deal with the objections already raised and not as starting the examination process afresh or reopening the same."
The Court held that the phrase "considered afresh" must be read in context. It did not authorize a de novo examination. The Court further noted that the Respondent itself admitted in its written submissions that the objections now raised were "fresh" and had never formed part of the record. This admission undermined the Respondent’s claim of statutory authority overriding the remand order.
The Court also dismissed the argument that public interest in patent grants justifies unrestricted examination powers on remand. While acknowledging the public nature of patent rights, the Court held that procedural fairness remains paramount, especially when a court has already intervened to correct a violation of natural justice.
The Court applied the principle from Kiran Thakur v. Krishan Lal and Kapil Satish Phalke v. Sub-Divisional Officer that the jurisdiction of an authority on remand is strictly confined to the terms of the order. Any attempt to expand the scope beyond those terms is ultra vires.
The Verdict
The Petitioner succeeded. The Court allowed the Interim Application and held that the Respondent is prohibited from introducing entirely new objections or new prior art references (D1 to D6) not part of the record as of the date of the impugned order. The fresh hearing must be confined to objections already raised in the FER dated 22.12.2020 and those raised during the hearing on 25.10.2021. The Controller may clarify or elaborate on existing objections but cannot introduce new grounds. The hearing must be completed and an order passed within eight weeks from the date of upload of this judgment. The effect of this order is stayed for four weeks to allow the Respondent to seek appropriate remedies.
What This Means For Similar Cases
Remand Orders Are Not Blank Cheques
- Practitioners must now argue that any remand order issued to cure a breach of natural justice cannot be used to circumvent procedural finality.
- A remand for "fresh hearing" does not equate to "de novo examination" unless expressly stated.
- The burden is on the authority to show that the remand order explicitly permits reopening of examination.
Patent Prosecution Is Not Exempt from Natural Justice
- Even in statutory regimes involving public interest, courts will enforce procedural fairness when a remand order is issued.
- Circulars and statutory powers cannot override a specific judicial order.
- New prior art introduced after a remand order will be treated as procedurally invalid unless the order explicitly permits it.
Strategic Implications for Applicants
- If a refusal order is set aside on natural justice grounds, applicants should immediately file an interim application to clarify the scope of remand.
- Any new objections raised post-remand should be challenged as ultra vires the remand order.
- Maintain a detailed record of all objections raised at each stage to establish the boundaries of the original record.
